In an election, 30% of the voters voted for candidate A whereas 60% of the remaining voted for candidate B. The remaining voters did not vote. If the difference between those who voted for candidate A and those who did not vote was 1200, how many individuals were eligible for casting vote in that election ?

Correct Answer: 60,000
ধরি, মোট ভেটারের সংখ্যা x A প্রার্থীর প্রদেয় ভোটারের সংখ্যা ( 30% of x) = 30x/100 = 3x/10 B প্রার্থীর প্রদেয় ভোটারের সংখ্যা ( x - 3x/10) × 60 /100 = 21x /50. ভোট দেয়নি তাদের সংখ্য = ( x - 3x/10 - 21x/50) = 50x - 15x - 21x/50 = 14x/50 = 7x/25 3x/10 - 7x/25 = 1200 15x - 14x /50 = 1200 x/50 = 1200 x = 60000
